McCAnRoLL, a the Webs may be sufliciently controlled and citizen of the United States, residing in guided to the platen of the t writing ma- Boston, in the county of Sufl'olk and Comchlne. These guides shift bzi c lfw monwealth of Massachusetts, have invented the c r on carriage, and serve to bring the certain new and useful Improvements in sheets laterally lIliJO alinement during such Type-Writing Machines, of which the folbackward h ng of h i g lowing i ifi ti Other objects and advantages will herein- This invention relates to typewriting maafter appe n. chines of the kind in which superposed plies I h mp y g d w g of web are led into the machine to be written Figure 1 is a Side t nBLl e Y ion f upon, copies being made upon the underlyall Underwood typewriting machine proing plies by means of carbon sheets.

Where the webs are of Fig. 4 is a perspective view of the carbon uniform width and arranged laterally in carrier, with a plurality of carbon-shifting register with one another, they may be blades of different lengths, respectively, guided by means of suitable side guides, as dapted to guide webs y 7 of corresponding is the custom; but where some of the-webs varying widths.

As it is desired that the. said shifting blades. typed items shall fall in certain columns-o Fig. 8 is a sectional view, illustrating one allotted spaces upon each web eonsidered of the carbon-carrying blades having a clip; widthwise, the main object of my invention the blade in this view being reversed, whereis to provide for the lateral guiding of narby the clip is seen upon the opposite edge row webs under these circumstances. 0f the blade from the position occupied '1' at To accomplish this purpose, I utilize the Fig- 2; and the car on Sheet accordingl is blades on said Wernery &' Smith machine folded back over the clip, so that the car on that project between the plies of web and ma extend from the blade in the same'genare used as carriers or shiftersfor carbon era direction as at Fig. 2. sheets. These blades are mounted upon a The loosely superposed-webs or plies 10,

The carbon sheets 16, webs. The webs may a1 be in alinement or interposed between the plies are attached register with one another along one side, but to blades or carriers 17, which extend 1nout of register along the opposite side; and wardly from the Sides of a carriage or slide the guides upon the carbon-shifting blades 18, which is a ranged in rear of the typeare utilized for confining as many of the writer platen, and has a handle whereby it ardly with as: i

19, andcorresponding guides. 20 mav be.

placed at the opposite" edge of the widest web. To guide any narrow web against a sidewise displacement, one end of the carbon-carrying blade, which underlies said narrow sheet, ma be turned up to form a sideguide 21. I said blade is to underlie a broader sheet, the end of the blade is bent reflexly, as at 22, to overlie a portion of the margin of the narrow sheet, so as not to stand. up under the overlying wide sheet; the reflex or bent end occupying so little room vertically as to be negligible. Thus, the narrow sheet is guided along one edge by the guide at the projectin end of the carbon-carr ing blade, and at t e other edge itis controllbd by the guides which are common to all of the webs. Hence, lateral displacement of any web is prevented.

These special guides 21 and 22 for the narrow sheets'are mounted onlyupon the carbon-carriage 18, but have sufficient control oven the narrow sheets to keep them substantially in their true paths, so that when they feed a'round'the platen they are in proper lateral register with the wide sheets and with one another. The backward thrust of the carriage or slide 18, upon which these blades are mounted, operates to adjust or true up along the edges such of the webs as may have become laterally displaced .in the rear otsthe carbon-carriage; and their registration is thus obtained with sulficient accuracy to servefor the usual purposes, so that the'typing---falls at the desired Widthwise portions of all the sheets.

The end of the carbon sheet 16 may be wrapped arqund its blade 17 and pasted back upon the body of the, sheet, as suggested in Fi 3; the web which is guided by the side guide 21 or 22, provided on said blade, lying upon the carbon. There is also illustratedat Figs. 2 and 6 the usual clip 23 for clipping the carbon sheet to the blade, and it will be understood that this clip is sufliciently, short to clear the reflex bend 22 of the blade which serves as a side guide and retainer for the narrow sheet. case, the said narrow sheet rests upon the surface of the clip.

It will also be understood that any narrow sheet may be guided on one edge by either one of the opposite main or general side guides19 or 20, and controlled at'theother edge by the guide at the end of the. underlying carboncarrying blade 17, as at Fig. 4, in which it is seen that the narrow,

In this sheets are not all in register at either side.

At Fi 7 is illustrated an arran ement b b in said Wernery & Smith patent, and also preventing displacement of narrow webs,

,thus substantially increasing the range of usefulness of the machine. The device is simple, inexpensive and compact, and not troublesome to use. Any blade may be detached fiom its seat A and replaced by another blade of greater or less length, having a side guide for the sheet at its free end, so that an assortment of blades of vary: ing lengths may render the machine adaptable-for a large variety of uses. The reflex or bent-back portion of the blade may serve to keep the carbon sheet from rising, especially during the backward thrust of the "carbon-carriage, which straightens out the webs, so that the webs cannot escape over the tops of the guides during the straightening-out operation.

Any of the carbon-carrying blades for the narrow sheets may be arranged upon either of the stepped supports seen at Fig. 4. If the blades have clips 23 thereon, as at Figs. 2 and 6, some of these clips will be in normal positions, forking over the rear edges of the blades, as at Fig. 2, while others will be in, reversed positions, forking over the front edges of the blades, as at Fig. 8;:and in the latter case, the carbon is placed wrong side out upon the blade, and is finally folded backover the clip, as seen at Fig. 8, so that the carbon extends from the blade 17 in the same direction as at Fig. 2. Thus, only one style of clip 23 needs to be employed for all of the blades. \Vhere the blades are mounted upon the left-hand supports, the clips 23 will appear as at Figs. 2 and 6; but if any blade is turned end for end and mounted upon the right-hand support, the carbon is to beheld thereon in the manner seen at Fig. 8.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others. Having thus described my invention, I claim: i

1. In a typewriting machine, the combination with means for leading loosely superposed webs of various widths interleaved with manifolding material to the printing awns? nation with means for leading a web and a carbon sheet releasably held together around a revoluble platen, of a shifter transversely attached to the carbon and havin a turn-up portion serving as aside guide or the web along one edge.
